Burg Neu-Windeck, Medieval castle ruins in Lauf, Germany.

Burg Neu-Windeck is a medieval castle that sits on a hilltop with a three-story residential building, additional structures, and a tall tower at its center. The layout shows how a noble stronghold was organized during the Middle Ages.

The castle was built around 1300 by the Windeck family and first appears in written records from 1371. In the 15th century, a long-standing conflict between two branches of the family came to an end through marriage.

The castle's chapel, documented in 1377, was dedicated to the Three Kings (Heilige Drei Könige). The two Windeck lines, Alt- and Neu-Windeck, shared the same coat of arms and were often at odds; the feud ended in 1466 when Berthold von Neu-Windeck married Anna von Alt-Windeck. The castle is also known as Burg Lauf or Laufer Schloss.

The castle ruin stands on the Schlossberg at 310 m above sea level southeast of Lauf. The bergfried can be climbed as an observation tower and gives a wide view of the surrounding area. The climb to the tower involves stairs and uneven ground in the ruined complex.

The 20-metre bergfried, the castle's main tower, contains three dungeons stacked one above the other. It can be climbed as a viewing tower and gives a wide panorama over the surrounding Ortenau countryside near Lauf.
